You might as well complain about Metalman which has technically started out as BUL* and only now has their own brewery. I have no doubt that their own version brewed in their new brewery will be just as good if not better than the white gypsy version.
I don't see anything wrong with BUL as long as it's done properly and to be honest, it only hurts the brand name if it's not.
*Not sure if it is technically BUL, but the principal is the same as how Sam Adams started out.
